# 3.09 x9

Lesson

Multiplication looks at equally sized groups. Can you solve this problem?

$8\times5$8×5

## Learn

9 groups is 1 less than 10 groups. Let's look at how we can use this to help us learn the 9 times tables.

## Apply

$5\times9$5×9

Remember!
• $9$9 groups can be thought of as $10$10 groups - $1$1 group.
• When we look at the answers up until $9\times10$9×10, the units have a descending pattern and the tens have an increasing pattern.
• When we add the digits in the answers to the nine times tables until we get a single digit, that digit is ALWAYS $9$9.
